Technical and commercial feasibility of manufacture of sodium silicateหัวเรื่อง: Sodium silicate | Supply and demandสารสนเทศออนไลน์: Click here to access full-text สาระสังเขป: However, these quantities include both solid and liquid forms of sodium silicate, as well as comprising alkaline and neutral types. Approaches to major users of sodium silicate showed that about 10 per cent of the demand is for the alkaline type.สาระสังเขป: No demand for sodium metasilicate has been found.สาระสังเขป: Part (I) Import statistics for Thailand show that for the year 1966, some 2085 metric tons of sodium silicate were imported, with a value of 2,467,884 baht. A demand projection indicates a usage of some 4,700 tons by 1972.สาระสังเขป: Part (II) Sodium silicate solutions are produced by fusing sodium carbonate and sand at a temperature of 1350 degree celsius. The resulting melt is dissolved in water and/or steam. Based on the sodium silicate consumption pattern in Thailand as described in Part I, a production unit with a capacity of 5000 tons of sodium silicate solutions, located in the surroundings of Bangkok is proposed.สาระสังเขป: Supplies of sodium silicate are at present derived wholly from imports although some material has been produced locally, and several companies are contemplating manufacture. Major users in Bangkok would welcome a local supply of sodium silicate, (provided price and quality are competitive) as it would reduce stock-holding and the nuisance of drum handling.สาระสังเขป: The main problem appears to be not so much one of encouraging local manufacture, but of trying to rationalize the several plans for manufacture so as to avoid over-fragmentation of the market. - Authors.สาระสังเขป: The required investment capital for this unit should be 1,700,000 baht. Total cost-price (before taxes) of one ton sodium silicate solution (50 % solids, Na2O/SiO2 ratio 1 to 2.0) is estimated at 790 baht ex-factory and at 810 baht delivered in Bangkok. This is well below (by about 200 baht) the present minimum import price. - Authors.สาระสังเขป: Usage is almost wholly in detergent powders and soap with small usages in metal moulding, carton closing and furnace construction. A potential, possibly large, market exists in water treatment.
